Hey all,
I had a student studying 6 units of science. They asked me what is the one thing they could do to make sure they didn't fall behind in class. They wanted to have finished the entire syllabus 4 weeks before trials but had a mountain of work they had to do each week. I designed this homework email so that they knew where they should be throughout they year. Small consistent study far exceeds cramming right before the exam. Having never missed a week of homework, my student ended up topping 3 sciences and getting a band 6 across all their units.
